Estimating the Energy Rate Function for Hydro Power Production Optimization
Operations planning at Manitoba Hydro is aided by using the Energy Management and Maintenance Analysis (EMMA) computer program. EMMA is a Linear Programming (LP) based model with the objective...
Managing Two Lakes with Significant Tailwater Fisheries
Norfork and Bull Shoals Dams on the White River in Arkansas were constructed in 1944 and 1951, respectively. The authorized purposes were for flood control, hydropower generation, and...
Water Basins in the Middle East
In Middle Eastern factional scheming for power, water is viewed as a strategic resource. The distribution of surface waters constitutes the basis for water geopolitics, thus representing...
Optimization of Water Resources Allocation Using the Modsim Model
The Fraser River Basin is located in north central Colorado west of the Continental Divide in an alpine basin with elevations ranging from 8,000 to 12,000 feet. Existing permanent resident...
Stochastic Optimization of Conjunctive Use in Pakistan
This paper describes an optimization analysis of conjunctive use of ground and surface water that incorporates stochastic inflows and regional variations in groundwater quality and availability....
Possum Kingdom Lake: The Impact of Releases for Fish and Wildlife
Possum Kingdom Lake is a 570,000 acre-foot reservoir on the Brazos River in Palo Pinto County, Texas, owned and operated by the Brazos River Authority (BRA). In 1985 the BRA applied to...
Optimizing Dallas' Multiple Reservoir Supply System
Dallas Water Utilities (DWU) applies a mathematical computer model of its reservoir supply system to assist in making operational decisions to optimize supply operations. The model considers...
Optimal Operation of Multiple Reservoir Systems
In this paper a temporal decomposition approach is presented to solve a long term deterministic model for a multi-reservoir system. Through relaxation the long term problem is broken into...
Old Ideas, New Applications: Expanding the State of the Practice
This paper describes three projects in which analytical tools were developed to assist decision makers in operating large-scale water resource systems. Position analysis models were developed...
Instream Habitat Considering Hydro-Peaking
Hydroelectric projects with storage have the characteristic of being able to generate electricity with short notice and to stop generating electricity with equally short notice. This peaking...
Application of Risk Management and Value Engineering Techniques to Evaluation of Water Resources Projects with Special Emphasis on Geological Hazards
The purpose of this paper is to provide: 1) a perspective for identifying and evaluating in comparable terms all hazards at a site; and 2) a means for intelligent decision-making based...
2-D Particle Tracking Model for Estuary Mixing
This paper presents the development and analysis of a 2-D particle tracking or random walk model for the simulation of transport in vertically well-mixed estuaries. The model was tested...
High-Country Hydro
The North Fork Stanislaus River Hydroelectric Development Project is a new 205 MW $267 million hydro plant in the Sierra Nevada Mountains. Completed in 1989, the project was the largest...
Possible Climate Change and Its Impact on Snowmelt and Water Supply in California
Global climate modelers are forecasting relatively large future climate change, with warming of 2 to 5?C. These changes, if they do occur, would have major impacts on California's...
Design of Steel Transmission Pole Structures
Transmission Losses, Flood Peaks, and Groundwater Recharge
Abstractions of streamflow in ephemeral stream channels from infiltration in the channel beds and banks are called transmission losses. These losses are important because water is 'lost'...
Experimental Investigation of Density-Driven Hyperconcentrated Flows
Lock-exchange type of laboratory experiments have been conducted in order to evaluate the dynamical characteristics of density-driven hyperconcentrated fluid mud. Fluid mud, confined in...
Activation and Degeneration of Turbidity Currents
Flow properties of the front of a turbidity current are investigated using the two layers model which takes into account of pick up and deposition of sediment. The amount of pick up rate...
Water Conservation in Los Angeles
The Los Angeles Department of Water and Power shares the responsibility with its customers of managing water resources by implementing water conservation measures that can be applied at...
Thermal Plumes from Staged Diffusers into a Uniform Quiescent Environment
The behavior of thermal plumes from staged multiport diffusers was investigated experimentally. The three-dimensional temperature distribution was measured by scanning thermistor rakes...
